BRIEF DESCRIPTION OF THE DRAWINGS
In the following, various exemplary embodiments will be described in greater detail with reference to the accompanying drawings, in which:
- FIG. 1 illustrates a simplified architecture of a system;
- FIG. 2 illustrates a signalling diagram according to an exemplary embodiment;
- FIGS. 3 to 6 illustrate flow charts according to exemplary embodiments;
- FIGS. 7 and 8 illustrate apparatuses according to exemplary embodiments.

DETAILED DESCRIPTION
The following embodiments are exemplary. Although the specification may refer to "an", "one", or "some" embodiment(s) in several locations of the text, this does not necessarily mean that each such reference is made to the same embodiment(s), or that a particular feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments.
Various exemplary embodiments may be applicable to any process in an industrial plant, including a processing system and/or an industrial manufacturing related process and/or a system for a technical process, which is at least partly automated, providing different measured/sensored values for a plurality of variables on one or more devices (equipment) and/or on one or more processes. A non-limiting list of examples includes power plants, pulp and paper plants, manufacturing plants, chemical processing plants, power transmission systems, mining and mineral processing plants, oil and gas systems, data centers, ships, and transportation fleet systems.
Different embodiments and examples are described below using single units, models, equipment and memory, without restricting the embodiments/examples to such a solution. Concepts called cloud computing and/or virtualization may be used. Virtualization may allow a single physical computing device to host one or more instances of virtual machines that appear and operate as independent computing devices, so that a single physical computing device can create, maintain, delete, or otherwise manage virtual machines in a dynamic manner. It is also possible that device operations will be distributed among a plurality of servers, nodes, devices or hosts. In cloud computing network devices, computing devices and/or storage devices provide shared resources. Some other technology advancements, such as Software-Defined Networking (SDN) may cause one or more of the functionalities described below to be migrated to any corresponding abstraction or apparatus or device. Therefore, all words and expressions should be interpreted broadly, and they are intended to illustrate, not to restrict, the exemplary embodiments.
In an industrial plant, an industrial automation device, for example a variable speed drive, may be located far away from an industrial asset, for example a motor that the industrial automation device is controlling. For example, the industrial automation device and the industrial asset may be located over 100 meters or even over 500 meters away from each other. A data connection between the industrial automation device and the industrial asset may be required in order to transmit sensor measurements from the industrial asset to the industrial automation device. However, due to the limited range of wireless communications such as Bluetooth or Wi-Fi, a wireless data connection between the industrial automation device and the industrial asset may not be reliable. Furthermore, a wireless signal may experience attenuation caused by, for example, concrete and/or other structural elements between the industrial automation device and the industrial asset. On the other hand, a separate wired data connection between the industrial automation device and the industrial asset may be impractical, as it may require hundreds of meters or more of additional cabling. In order to address this challenge, some exemplary embodiments provide a data connection between an industrial automation device and a sensor device by using both wireless connectivity and an existing cable, for example a power cable or a PtlOO cable, between the industrial automation device and the industrial asset.
FIG. 1 illustrates a system according to an exemplary embodiment. It should be noted that FIG. 1 illustrates a simplified system architecture only showing some elements and functional entities, all being logical units whose implementation may differ from what is shown. The connections shown in FIG. 1 are logical connections; the actual physical connections may be different. It is apparent to a person skilled in the art that the systems also comprise other functions and structures. It should be appreciated that the functions, structures, elements, and protocols used in or for communication are irrelevant to the exemplary embodiments. Therefore, they need not be discussed in more detail here.
The system comprises one or more sensor devices 101. The sensor device 101, for example a smart sensor or an intelligent sensor, may be a condition monitoring sensor that may be attached to, or comprised in, an industrial asset, i.e. machinery. The industrial asset may comprise for example a motor, such as an induction motor, a pump, such as an electric pump, a fan, a compressor, an extruder, and/or a mounted bearing. The sensor device 101 may be configured to measure operational information, for example observed technical performance information such as measured values for temperature and/or vibration associated with the industrial asset. The sensor device 101 may measure, for example, operational information associated with the motor, fan, compressor, extruder, or mounted bearing comprised in the industrial asset. The sensor device 101 may be configured to store the measured operational information for example in an internal memory of the sensor device 101. The sensor device 101 may be able to connect to the internet for example via a cellular or wireless link, and the sensor device may be further configured to store the operational information for example to a cloud server. The sensor device 101 may be equipped with a short-range radio interface, for example Bluetooth, Wi-Fi, or a wireless mesh protocol. The sensor device 101 may be further configured to exchange information, i.e. to transmit and/or receive data, with a first gateway device 102 via a first wireless connection 110, for example a Bluetooth or Wi-Fi connection. For example, the sensor device 101 may be configured transmit the measured operational information to the first gateway device 102 via the first wireless connection 110. The sensor device 101 may be further configured to analyze the operational information, for example to detect and/or predict a fault associated with the industrial asset, and to transmit a warning if a fault is detected or predicted. For example, a fault may be detected if a measured value, such as temperature, associated with the industrial asset exceeds a predetermined threshold value.
The first gateway device 102 may comprise for example a Bluetooth gateway, an access point, a server computer or a terminal device, such as a smartphone, a desktop computer, a laptop computer or a tablet computer. The first gateway device 102 may be attached to the industrial asset, or located at a close proximity to the sensor device 101, for example less than 10 meters away from the sensor device 101, depending on the range of the wireless technology used by the gateway. For example, the first gateway device 102 may be comprised in a junction box or a terminal box of the industrial asset comprising cabling connections for the industrial asset. The first gateway device 102 may be configured to exchange information, i.e. to transmit and/or receive data, with the sensor device 101 via the first wireless connection 110.

The first gateway device 102 may be connected to a second gateway device 103 via a wired connection 111. The wired connection 111 may comprise for example a power cable or a PtlOO cable. A PtlOO cable is a type of sensor cable that may exist between the industrial automation device and the industrial asset. However, the sensor device 101 may not comprise means for connecting directly to the PtlOO cable or to the power cable. The power cable, for example a three-phase symmetric power cable, may be used to provide power from an industrial automation device 104 to the industrial asset. Power line communication may be used to transfer information via the power cable. The power cable may also be used to provide power to the first gateway device 102 and the second gateway device 103. The first gateway device 102 may be configured to exchange information, i.e. to transmit and/or receive data, with the second gateway device 103 via the wired connection 111. For example, the first gateway device 102 may be configured to transmit the operational information and/or warning(s) to the second gateway device 103 via the wired connection 111.
The second gateway device 103 may be configured to exchange information, i.e. to transmit and/or receive data, with the first gateway device 102 via the wired connection 111.

The second gateway device 103 may be attached to, or comprised in, the industrial automation device 104, or located at a close proximity to the industrial automation device 104, for example less than 10 meters away from the industrial automation device 104, depending on the range of the wireless technology used by the gateway. The second gateway device 103 may be configured to exchange information, i.e. to transmit and/or receive data, with the industrial automation device 104, for example a control panel of the industrial automation device 104, via a second wireless connection 112, for example a Bluetooth or Wi-Fi connection. For example, the second gateway device 103 may be configured to transmit the operational information and/or warning(s) to the industrial automation device 104 via the second wireless connection 112. The second gateway device 103 may comprise for example a Bluetooth gateway, an access point, a server computer or a terminal device, such as a smartphone, a desktop computer, a laptop computer or a tablet computer.
The industrial automation device 104 may comprise a frequency converter, variable frequency drive, variable speed drive, motion drive, motion controller, motor, servomotor, AC/DC module, DC/AC module, DC/DC module, programmable logic controller (PLC), switch, soft starter, robot, or any other device used for industrial automation. The industrial automation device 104, for example a variable speed drive, may be used to run machinery, which may also be referred to as an industrial asset, such as a motor, a pump, a fan or a compressor, at different speeds. The industrial automation device 104 may be located for example over 100 meters away from the industrial asset and from the sensor device 101. The industrial automation device 104 may comprise or be connected to a controller, for example a proportional-integral-derivative, PID, controller. The controller may be configured to send control signals to the industrial automation device 104. The industrial automation device 104 may control highly dynamic industrial processes, in which for example the speed or the torque applied to a motor has to be varied according to the needs of the industrial process.
The industrial automation device 104 may store, for example in an internal memory of the industrial automation device, information on control parameter settings, for example present values of parameters such as controller gains, ramp times, motor data, limits, magnetization settings, signal filtering settings, and/or motor control settings. The industrial automation device 104 may also store internal technical information recorded during the operation of the industrial automation device, for example information on key performance indicators, such as load current histogram, torque ripple, torque vs. speed curves, and/or power vs. speed curves, temperature, voltage, current, and/or other information such as resonance frequencies and/or load inertias. The industrial automation device 104 may be equipped with a short-range radio interface, for example Bluetooth, Wi-Fi or a wireless mesh protocol. The industrial automation device 104 may be configured to exchange information, i.e. to transmit and/or receive data, with the second gateway device 103 via the second wireless connection 112. For example, the industrial automation device 104 may be configured to receive the operational information and/or warning(s) from the second gateway device 103 via the second wireless connection 112. The industrial automation device 104 may be further configured to adjust or optimize one or more of the control parameter settings of the industrial automation device 104 based on the received operational information associated with the industrial asset in order to improve the efficiency and/or reliability of the industrial automation device and/or the industrial asset. The industrial automation device 104 may be further configured to stop the industrial asset, for example to cut power to the industrial asset, if a warning is received or if the received operational information indicates overheating by the measured temperature value exceeding a pre-defined threshold value, as an example. For example, the industrial automation device 104 may use model predictive control or a PID controller to adjust the one or more control parameter settings. The industrial automation device 104 may further be configured to transmit one or more commands to the sensor device 101 via the second gateway device 103 and the first gateway device 102.
FIG. 2 is a signalling diagram illustrating information exchange according to an exemplary embodiment. Referring to FIG. 2, a sensor device, for example a smart sensor, measures 201 operational information associated with an industrial asset. The industrial asset may comprise for example a motor, such as an induction motor, a pump, such as an electric pump, a fan, a compressor, an extruder, and/or a mounted bearing. The operational information may comprise for example observed technical performance information such as one or more measured values for temperature and/or vibration associated with the industrial asset. The sensor device then transmits 202 the measured operational information to a first gateway device via a first wireless connection. The first gateway device then transmits 203, or forwards, the measured operational information to a second gateway device via a wired connection. The second gateway device then transmits 204, or forwards, the measured operational information to an industrial automation device via a second wireless connection. The industrial automation device may then adjust 205, or optimize, one or more control parameter settings of the industrial automation device based on the received operational information associated with the industrial asset in order to improve the efficiency and/or reliability of the industrial automation device and/or the industrial asset. The industrial automation device may, for example, cut power to the industrial asset, if the received operational information indicates overheating by the measured temperature value exceeding a pre-defined threshold value, as an example. Furthermore, the industrial automation device may transmit 206 one or more commands, or configuration parameter settings, to the sensor device via the second gateway and the first gateway. For example, the industrial automation device may instruct the sensor device to adjust a sampling rate, or time scale, for the measurements performed by the sensor device. The sensor device may then adjust 207 the sampling rate of the measurements based on the one or more commands received from the industrial automation device. For example, the sampling rate may be increased in order to increase the resolution of the measurements, or the sampling rate may be decreased in order to reduce power consumption and thus increase the battery life of the sensor device (if the sensor device comprises a battery).

FIG. 5 illustrates a flow chart according to an exemplary embodiment. Referring to FIG. 5, the second gateway device receives 501 the operational information transmitted by the first gateway device via the wired connection. The second gateway device then transmits 502 the operational information to an industrial automation device, for example a variable speed drive, via a second wireless connection, for example a Bluetooth or Wi-Fi connection.
FIG. 6 illustrates a flow chart according to an exemplary embodiment. Referring to FIG. 6, the industrial automation device receives 601 the operational information transmitted by the second gateway device via the second wireless connection.
A technical advantage provided by some exemplary embodiments may be that using a combination of two wireless connections together with a wired connection may improve the range, data transfer rate, and/or reliability of connectivity between devices that are located far away from each other, for example in comparison to using only one Bluetooth or Wi-Fi connection between the devices, which may not have other means of connectivity with each other. In addition, the amount of physical cabling needed between the devices may be reduced for example in comparison to using a separate data cable, such as an ethernet cable, between the devices.
